Coats' disease with macular oedema responsive to aflibercept and argon laser.

CLINICAL CASE: A 14 year-old boy with Coats' disease in his right eye, presented with a visual acuity (VA) of 0.1, micro-aneurysms, exudates, a macular oedema of 959 microns, and peripheral telangiectasias. After 12 months follow-up with 6 ranibizumab injections and 3 sessions of argon laser photocoagulation, the macular oedema remained and VA was 0.2. Following 4 aflibercept injections and another 2 laser sessions, he had a good foveal slope and a VA of 0.5, with no recurrences in the last 12 months. DISCUSSION: Treatment with aflibercept and argon laser was effective in our patient with stage 2B Coats' disease and macular oedema unresponsive to ranibizumab.
